IBEAD-SHAPING TOOL.

Application filed May 9,

This invention relates to an improvedtinners bead-shaping tool, andseeks, among other objects, to provide a tool especially adapted foropening the flattened end of the bead of an eaves trough or the like andshaping the end of contour.

T he invention seeks, as a further. object, to provide a tool which willeliminate the the bead to its'natural I0 hazard heretofore experiencedin opening the end of a flattened eaves trough head so that injury tothe operator will be precluded. Still another object is to provide atool which may be readily forced into the flattened end of a bead andthen operated with facility for shaping the bead.

And the inventionseeks, as a. still further object, to provide a toolwhich will be of simple construction, sturdy and efficient.

Other and incidental objects will appear hereinafter.

In the accompanying drawings:

Figure 1 is a perspective view showing my improved tool in connectionwith a conven- 5 tional eaves trough.

Figure 2 is a plan view of the tool.

Figure 3 is a. detail sectional view on the line 33 of Figure 2, lookingin the direction indicated by the arrows.

In carrying the invention into effect, I employ a pair of crossed leversand 11 pivotally connected by a bolt or other fastening device, whileeach of said levers is formed with an angularly disposed forward endPortion 12, which end portions lie substantially parallel when the jawsof the levers are closed. Formed on the portion 12 of the jaw 10 is anaxially alined cylindrical jaw 13 having a tapered nose 14 which is thusreduced in size and, as best shown in Figures 1 and 2, said nose isformed with flat side faces 15 substantially parallel to the flat sidefaces of the lever. The nose is thus substantially wedge-shaped, but is,never- 5 theless, provided with rounded upper and lower edges. Formed onthe portion 12 of the lever 11 is a semi-cylindrical jaw 16 adapted tooverlie the jaw 13 seating fiat thereagainst. The jaw 16 is of a lengthto extend from the rear end of the jaw 13 to the base of the nose 1 1 ofthe latter jaw so that the jaw 13 thus projects beyond the forward endof the jaw 16 and, as shown in Figure 1, the portion 12 of the lever 11is continued along the baokof the jaw 16 to form a reinforcing rib17therefor.

In Figures 1 and- 3 of the drawings, I have shown the manner in whichthe tool is used. A length of conventional eaves trough is indicated at18 and the cylindrical bead thereof at 19. In any instance where itbecomes necessary to cut off an end of a length of trough, the bead isunavoidably flattened atits adjacent end. Accordingly, before anotherlength of trough can be properly sol dered to the severed end of theformer length, it becomes necessary to open and reshape the flattenedend of the bead in order that one end of the second length of trough mayproperly mate with the adjacent end of the first length mentioned.I-Ieretofore, it has been customary to employ a screw driver, coldchisel or the like for opening and reshaping the flattened end of such abead. However, such tools have not only proven inefficient and unhandy,but injury to the operator has often been caused bythe sudden opening ofthe bead, withthe result that the hand of the operator, in plungingforward, has been out against the sharp edges of the bead and trough.The present invention has, therefore, been devised with a view ofovercoming these disadvantages.

Initially, the lever 10 is grasped and the nose 14 of the jaw 13inserted into the flattened end of the bead, and, in this connection, itis to be observed that, in cutting a length of trough, the bead is, asshown in Figure 1, always flattened in such manner that the free innermargin of the bead lies substantially parallel to the adjacent side ofthe trough. In other words, the bead is elongated against the adjacentside of the trough. Accordingly, when inserting the nose 14 in the head,the fiat faces 15 of said nose are presented to the sides of theflattened end of the head. The nose will, therefore, be guided into thebead by said faces while the tool will be located by said faces in suchmanner that the jaw 16 will be dis posed over the upper side of thebead.

Having initially insertedthe nose 14 of the 13, the lever 10 is pushedforwardly for forcing the jaw into the head and since the lever 11crosses the lever 10, the latter lever will, should the bead suddenlyopen to permit the jaw to plunge forwardly, engage the end of the troughfor limiting the lever 10 in its forward movement and thus preventingthe hand of the operator from being injured against the end of thetrough. As the jaw 13 is forced into the bead, as indicated theflattened-end of" the bead will, or": course be" opened by said jaw"sothat the lever 11 may then be grasped for swinging the jaw 16downwardlyagainst the-bead,

when, by rotating the'jaws"with'respectto the bead and compressing thehead -there between, the flattened end' of the bead may,

as; shown in Figure 3,bexiieadily':reshaped to its natural cylindricalcontour. As will beperceived, the tool maybe operated with one hand ofthe opetratorto aceo-n' plishj the entire reshapingoperation of thebead, so

a that should the trough be suspended in place at the eaves of a roof,the other hand ofthe operator 'will be 'free to graspa ladder.'Accidents such as might otherwise 0c cur,"will aeeordingly be avoided.
